It is usually not all numbers. It can be all variables, such as area of a rectangle = L*B where L and B are the length and breadth. But to use the formula it is necessary to substitute the numerical values of the variables.
There is no limit to the number of variables a formula can have.
you add all the numbers together then divide the answer by the number of numbers there are
That sounds like the definition for Recursive Formula.
In general math, a formula is an equation that expresses an idea or theory. For example, the slope-intercept formulaequals y=mx+b . Formulas don't always have numbers, but they most commonly have variables. Variables are lowercase letters that represent real numbers. Answered by: QWERTYIt's a calculation
you add all the numbers and divide by how many numbers there are by the answer you get when tou add all the numbers
There is no limit to the number of variables a formula can have.
A Formula
A formula is a mathematical expression that contains symbols, numbers, and operators to perform a calculation or define a relationship between variables. The simplest form of a formula is one that is clear, concise, and does not contain unnecessary elements or complexity.
If you had a formula you would plug numbers in for the variables and solve for the other variables create a list of coordinates (data points). Next you would graph those points and connect the dots.
You can do all the calculations with variables - add the numbers, and divide by the size of the set. Of course, you'll probably end up having variables in the average as well.
complex numbers
In mathematics, a formula is a statement that expresses one variable as a function of one or more variables. To find the value of any one variable you will usually need to know the values of all the other variables. These values are plugged into the formula and the result is calculated.
